Expandable Battery Pack

B300S has a 3,072Wh capacity and lasts 3,500+ cycles to 80% of its original capacity. Hook up 6 B300S packs with AC500, and you'll get a massive powerhouse with 18,432Wh, enough to power up your RV, off-grid life, and get you through a severe power outage.

Responsive Even in the Cold

Waking up electronics on a freezing day may be time-consuming. But with the Self-heating Function, B300S will automatically heat up the battery to ensure it can work actively and smoothly as usual. Note: Self-heating Function won't be activated if the ambient temperature is under -4℉.

Standalone Power Source

More than an expansion battery pack, B300S can be used as a standalone power source as it features versatile outputs - 100W USB-C, 12V/10A cigarette lighter, and 18W USB-A to feed your smartphones, laptops, fans, lights, refrigerators, and more.

Flexible Recharging

BLUETTI B300S takes up to 500W AC, solar, or car charging.

Blazing Fast Recharging

Faster is always better. Charge your B300S in 4 hours* at the maximum of 1,000W input rate by 1,000W Solar input* or 500W adapter with 500W solar input. * The data is for reference only. * The D050S DC charging enhancer is required.

Never Run Out of Power

AC500 powers your devices like a gas generator, but without any fuel costs, noise, and pollution,
making it safe enough to use next to you whether you're at home, pitching a tent, or trying an RV road trip.
